8 Claims, 4 Drawing Figures TOY AIRPLANE FIELD OF THE INVENTIONTheinvention relates generally to toy airplanes The invention hasparticular application in toss-type toy airplanes.

BACKGROUND OF THEINVENTION Small toss-type airplanes have been popularfor'many years. These toss-type toy airplanes range from the home-madeairplane assembled from paper to more elaborate Commercial types. In thepast, the commercial type toss-type airplanes have been either difficultto assemble or lacking in durability.

SUMMARY OF THE INVENTION It is an object of the present invention toprovide a toss-type toy airplane which can be readily assembled andwhich can withstand considerable use.

It is a further object of the present invention to provide a toss-typeairplane which can be easily weighted to provide an aerodynamicallysound vehicle.

The toss-type airplane of the present invention is comprised of aunitary fuselage section which has a BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a perspective view of the toss-type toy airplane of thesubject invention in its assembled form;

FIG. 2 is a sectional elevational view of the toss-type toy airplane ofFIG. 1 taken through line 2-2;

FIG. 3 is a sectional elevational view of the toss-type toy airplane ofFIG. 1 taken through line 3-3; and

FIG. 4 is an exploded view of the toss-type toy airplane of the subjectinvention showing the individual parts thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment of thesubject invention is shown in the drawings. Essentially, the toss-typetoy airplane 2, best seen in FIG. 1, is comprised of a fuselage section4, a wing section 6 and a nose cap 8.

As best seen in FIG. 4, the fuselage section 4 is a unitary pieceprovided with a flattened upper surface 10. The body section of thefuselage 4 is configured in an essentially circular cross-sectionalshape as best seen in FIG. 3. A configuration other than circular ispossible, however, for best aerodynamic performance the essentiallycircular cross section has been'found to be most preferable in practice.In practice, polyethylene, or similar conventional plastic materialshave been found to be suitable materials for use in the fuselage section4.

The wing section 6 is provided with a main wing section 14 which isconfigured in the classical swept back mode and a forward section 16which is swept back at a more pronounced angle than-the main wingsection l4. Ailerons l8.and 18' are also provided. The ailerons '18 and18' are integrally formed with the, wing structure 6. The ailerons 1 8and;.-l8' arebentalong fold lines 20 and 20"re.spectively-and canbe-elevated toany desired angle. In practice it has been found thatanangle of approximately -5 to and preferably 20--provides the bestaerodynamic characteristics for. th e toss-type toy airplane of thesubject invention. An empennage section comprised of twin vertical tails22 and 22' is also provided. The twin tails 22 and 22' are alsointegrally formed with the wing member 6 and are folded upwardly alongfold lines 24 and 24 The twin tail members 22 and 22 can be configuredin virtually any conventional tail shape. However, in practice it hasbeen found that for the application in the present toss-type toyairplane, the tail sections 22 and 22' should be provided with a curvedleading edge 26, 26' and a flat upper edge 28, 28' which when in theassembled state is essentially parallel to the wing surface 14. Inpractice it has been found that polyethylene, or similar conventionalplastic materials provide suitable material for use in the thin wingsection 6.

The nose member 8, best seen in FIG. 2 is shaped in the form of a cap.The nose cap 8 can either be completely circular in cross section asshown in FIG. 4 or can be provided with a flattened upper surface 30 asbest seen in FIGS. 1 and 2 to conform to the contour of thefuselagecross section 4.

In the assembled state, the wing section 6 is fixedly adhered to theupper surface 10 of the fuselage 4. For aerodynamic balance it isnecessary that the longitudinal center line of the wing section 6 beplaced on the flat glue surface 10 of the fuselage. Although a glue hasbeen found tobe the most suitable adhesion means for connecting the wingsection 6 to the flattened surface 10 of the fuselage section 4, otherattachment means such as staples can be used.

The final step in the assembly of the toy airplane is the placing of thenose cap 8 on the nose of the fuselage 4. The nose cap 8 can be glued orotherwise fixed to the fuselage 4. However, in practice it has beenfound that the nose cap 8 should be sized to force-fit on the airplaneto provide the best results. The nose cap 8 affords the dual benefits ofproviding a weighted member to contribute to the aerodynamic balance ofthe toy airplane and means to assist in retaining the leading edge ofthe wing section on the fuselage 4.
